🔐 Hash Generator (SHA-256)
Paste text or pick a file to get its SHA-1, SHA-256, SHA-384 and SHA-512 digests at once. Hashing runs in your browser with the built-in Web Crypto API, so even large files never leave your device.
SHA-1
— SHA-256
— SHA-384
— SHA-512
— MD5 is not offered: browsers do not implement it, and it has been broken for years — use SHA-256.
🔒 Runs 100% in your browser. Your data never leaves your device.
How to use
- Type or paste your text. All four hashes update instantly.
- To hash a file, click ‘Hash a file instead’ and pick it — the file is read locally.
- Click Copy next to the digest you need.
FAQ
Where is MD5?
Browsers do not ship MD5 in the Web Crypto API, and MD5 has been considered broken for collision resistance since 2004. For checksums or integrity, use SHA-256.
Are my files uploaded?
No. Files are read with the FileReader API and hashed locally with Web Crypto. Nothing is sent to a server.
Can I verify a download checksum?
Yes. Hash the downloaded file here and compare the SHA-256 digest with the one published by the vendor.
